EXTENSIBLE TABLE.

Application filed May 23,

To all whom it may concern Be it known that l, ISAAC CooxLiN, a subject of the King of England, and residing at Liverpool, in the county of Lancaster, England, have invented improvements in or Connected with Extensible rlables, of which the following is a specification.

This invention has reference to extensible tables of the kind in which one vor more leaves can be automatically moved into position when extending the tables, and also moved out of position and stowed under the table top in contracting the table; and it relates moreover to that type of table where the leaf or leaves is or are brought up from a resting or stowing portion of same, which is constituted by the slide frames of the table, which extends between the two ends; means being employed for moving the two end portions' farther from and nearer to each other.

In the table hereinafter described, the improvements under this invention are comprised.

In a round or oval table according to this invention, the sliding frames are disposed in lines at points well within the outside edge or sides of the table top, and therefore are relatively close together; and the table top is provided all round with a deep flange or skirting of wood, and the leaf or leaves is or are similarly provided with a deep flange or skirting; and when a leaf is in position the edges of its flanges join up with the edges of the flange or skirting, so that the flange or skirting is continuous when the leaf is in; and the table and parts are so adapted and arranged that when a leaf is removed, and the end parts closed up by the operating screw or means, and the leaf stowed underneath, the two edges of the flange or skirting come together; so that a continuity of this flange or skirting always exists; that is there is never a gap in it.

Further in tables of the kind referred to, the edge portions of the leaf are hinged to the central portion of the leaf aild so adapted that when the table is opened, these hinged portions will foldmsay fall down; and when the leaf passes down below the top, and the table closed up by the operating gear, these hinged edge portions of the leaf will not be visible from the side of the table, they being within the parts of the table connected with permanent ends. In the case of a round or oval table, the foldable parts lie within the 1922. Serial No. 563,137.

depending flange or skirting portion of the permanent ends of the table, and therefore will be out of sight, and out of the way; and when the leaf is moved into position, and its hinged end parts moved up into position of use, the edges of the flange or skirting will be in line with and engage the edges of the flange or skirting of the table end parte, and so form a continuous flange or skirting; and these leaf end parts, which consist of a short length of the leaf top and the skirting, may be provided with dowels or dowel apertures (the table end top portions being correspond: ingly furnished) so 'that when the table is closed after bringing up and inserting a leaf, these hinge or folding end portions will be held in position and the edges of the leaf flange or skirting may also be grooved and tongued so as to engage with corresponding formation of the edges of the skirtings of the top.

ln some cases the hinged end parts of the leaf may be moved automatically into position when the leaf is being inserted in extending the table, and this may be effected by connecting the underside of the leaf by a pivot joint with a bar on the underside of the stationary part or table top, and so arranged that when the table is opened, and the leaf brought up, the jointed ends of the leaf will be moved up into proper' position, and vice versa, lowered when the leaf is moved down, and the table closed up.

'll he invention is illustrated in the annexed drawings in which Figure l is a plan with part of the table-top removed or broken away, and Figure 2 is a longitudinal section. Figures 3, 4 and 5 are elevations showing apart of the table to a larger scale; and Figure G is a view of a slotted link method of operating the leaves.

rlhe table shown in the drawings is of the character referred to having two removable leaves, and two semi-circular end,

portions l, and a central portieri 2. The slide frames consist of two sets of outside slides 3 and cross frames 4l, attached to the top of each end of the table l. These frames have no legs attached to them, and are wholly carried by the table top. Between the slides 3 are inner slides 5 attached to the top of the centre portion 2 of the table, connected to and sliding in or on the outer slides 3 by a tongue and groove arrange ment in the known way; and the slides 5 are connected together by erossbars @,and when, the table, is closed` with they leaves stowedy under the table top, the end bars 6 of the slides 5 come near the endv bars 4 of the outer slides 3.

The table tops l, the centre portion2 and the leaves l0 all have a deep depending flange or skirting ll Within which theslide frames 3 and 5 lie, the slides being relatively close together, thatis, arelativelyy large distance towardsy the centre of the table from the skirtings, ll; and the legs l2 of` the.

table, are all attached lto this( skirting or flange ll; and as willbe seen one leg is fixed ateaclrof the angles offt'he inner face or edgeofithe table-top portionsl, and one is, at eachfangleof the centre portion 2, so thatwhen `the tableis in its smallest dinien sion, with bothleaves stowed, the legsv of the, anglesofof the ends, and those ofthe centre portion lieJ close together asshown. Attheronnded portion ofthe ends 'l there are.` intermediate legs l2attached to the skirting,- between those, at` the i angles..

Aleafahas two bars 16 with an inclined frontportion finishing at the front edge, and lprojeatingA portionsl at the other end beyondthe other edgevof `the leaf, which aetras-weightsg and when a leaf is inoposition in thetable, thesepartscoine on the under surface of the table top, and inconttl Withjit; whilstf'when the leaf is being pulled `up .from underneath' froinits stowed position, its inclined ends strike the block 17 fgonwthe frames 3;, 4l, or 5, G, andlthey are.

lifted into yposition level with the table top. OnV the leaf there are stops le. against which-projections 15,011 the frames 3- eome i slides action the inclined ends of the bars liof the leaf, and ca .Je the leaf to slide back` and downunder the middle portion 2 y ofthe table top. l

ln the working of4 the table when the angles at the bottom of the incline of the bars 16 of the .leaffreach `the, top ofthe ineline of they blocksl?, the leaf overbalancesv` from theincline to the horizontal position, the point or angle of the bar 16 beingsnch a distance,r from the` front edge of the leaf aste cause this action.

When the back,y edge of a leaf is pulled ont ofthe dowelsin the. top 2 byk the partsl 14,15 as described, its back end is free. to fall,and does fall down, into the bottom of the cutaway slot 18 inthe Aslides 5 in the known way of tables havinfstovvable leaves of the kind concerned.

The leaf is.inoved npinto position whenv edges ofthe leaf and the table is operated, by a slotted link 20, carried and pivoted byv a bracket 2l to the table top l; and it is connected with the bars 16 of theleaf byv headed pins 22 fixed to the bars, and passing through the slots and these parts are so arranged that when the table portions and 2 are moved away from onel another by the operating screw 7 and nut 8 on the cross bar hereinafter de scribed, the leaf ifs-pulled up intoposition; while 'when the leaf is to be. lowered, it falls into place and is moved into the slots lSin the known way.

7hen ythe pin 22 lirstpulled by the link, bjf the end of the .l alot Corning against the pin, the lower angleof the inclinedends of the bars lf3 will just touch the forward end or `point of the blocks 17.

lheleaf at eachA end has a. foldable part. or flap, 24, carryingnnder it a skirting part ll, and it is connectedtouthe bodyof the leaf by a inetali hinge. 25 screwed to 'both parte, the pivot of the hinge being ata point distant from, theouter edge ofthe leaf body slightly less than the 'thickness of thelcaf; andthe outer part26 of the body on the npperside is shaped to this radius,

leaj: v i an rlp wardly projecting ledge Ion the body `l tely: above lthe hinge axle.l he

inner edge of the hinge and liap part 24% has correspon din y cnrvedgroove of thesame radins, and having Athe same centre,l so th at Wl' the flap 2d is up, and in position in tbe/table, the inner? rippen edge; ofzlithe flap will i lieI in i lContact ywith I theV- upwardly f pro 1 jectingf partof the leaf `body above the hinge axisgwhile whenitheleaf is ,stowed in the slots under .the tabletop, the leaf flaps 24 will hang down in positionas, shown in Figure 3.;

llfben the tableis open, and the edgesof the topand-the leifleave one another, the flapa2ll are free` to `fall downhbont theiry hinges; but when` the leaf 4is vnfmved into po-M sit' n; thepflaps 24,- are moved into ,the honi-g zontal positimi by ligand, and beld there until the edges of the top and leaf nieet when tongues and grooves 27 on there` spectivenieeting edges of the slzirtings k1l onevanother, and,engage` so that the flape 2% are held Iin position` lVhen the flaps are in thisgnosition the slrirtings. ll of top and leaf or leaves are continuons ronndthe t-aliile. l

llhen the flaps 24 are down `they-lie Within the space, between. the skirting l1, and ythe. frames and the fralinesfl, 5,can be, soared apart, about the proportion of "thelltotal width of table shown,

ln the case of aidoluble leaf table, thel aveinents ofy the'parts are.efl'ccted'by` a l one comprisinga cross `bar28 (on which the screivfnnt` is fixed) theends of which slide in groovesin the inside of theinner slides 5, as shown in dotted lines marked 29;

Whilst enotliei" cross bei' 30, connectedto it by longitudinal bers 31, is connected to the end slide trames 3 remote :from the screw 'i'. B v iotating the screw 7. the outer entl of the treme 3 is lirst moved :incl the ve rions fictions of movingthe leaves into an outer position in the table topj end stowing them in the known mennen be effected, the cross bers on the veious renies suoli es 6, 253, and 32 coming; in Contact with eeeli other to produce the (lesirecl effect 'incl movement.

'ln the ense of a table having more then two leaves, the centre portion 2 of tbe tei-ble would be split in two, and :i lest would Werl; in between these two parts.

ln some ceses, instead of tivo leaves being opeietecl 'from one end b v e single sofevv7 the tivo ends in i table and leaves eoulfl be Worked by screw fvoin eeoli endL o?? the table; in which cese eeoli screw would be supported in e bearing on the insitle oi the shifting il, and Work in e nut Connected with e member oit each ot tbe 5r-:mies incl in the oase of e single leali table, tbe slides olf each envi would be 'fixed to the top of' the seme, :incl one slide would be Within the other similarly es the frames or slides 5 slifle in the frame 3; :mol 'when such a table has semi-circuler ends, the table will be cilL cular when the leef is stowed, enel tbe table closed; und these tivo ends would be similaito the encls of the table shown in the draw ing. Also in some ceses the slides 3 een extend along the end up to the inside of the shifting il.

lhet is claimed is in extension table7 including end frames anzi :t central 'frame eemfying teble top portions, loose leaves carried between tne trames having projections theeon, said central freine having projections to eooperete with the projections on the leaves.,A links pivotelly mounted on tlie end frames having a. limited sliding connection with the adjacent loose leef, end operating ineens for relatively moving the filen'xes, whereby the links Will move the leaves to (reuse e cooperation of the pojeetions foi' raising the leaves into top :forming position in one operation of 'the treines enel the projections will cooperate in e subsequent operation to Stow the leaves.
